The Lowdown

Alright mate, Rusty here. Let’s break down what’s on the cards for us over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows that are gonna get the blood pumping.

The water’s sitting at a pretty normal 72°F, nothing unusual for this time of year. We’re kicking off this Saturday, the 29th of August, with small and clean waves at Jaconé. The morning session is a bit average with some 2 ft S swell, but the afternoon cleans up nicely as the wind shifts cross-off, with a 3 ft easterly swell rolling in. The energy is moderate (235), and the waves will be clean, but it’s hardly a standout. Sunday the 30th is a write-off with messy cross-onshore winds, so don’t bother.

Now, Monday the 31st is where it starts to get interesting. The morning is looking sweet: a clean 6 ft ENE swell with a light offshore breeze. The energy is solid (619), and the conditions will be clean for a fun session. The afternoon holds up too, with a 4 ft wave and light cross-off winds. That morning window is the best of the early run.

We then hit a bit of a dry spell from Tuesday the 1st through to the end of the week. The first half of September brings some hefty swell, but it’s all too messy. On Wednesday the 2nd, we get a strong 13 ft SW groundswell (energy of 4601), but it’s accompanied by strong onshore winds and poor conditions. Thursday the 3rd is similar – a big 10 ft SSW swell (energy 1756) with cross-off winds, but it’s just too big for this spot. Kite surfers might be more interested here than paddle surfers.

Friday the 4th sees a drop back to a clean 5 ft SSE swell with offshore winds – a solid fun wave, but nothing to write home about. Saturday the 5th is a tease: the morning serves up a glassy 4 ft SSE swell, but the afternoon turns to rubbish.

The second week starts with a bang on Monday the 7th of September. We’re looking at a massive 13 ft S groundswell with glassy conditions and zero wind. The energy is through the roof (6265), but this is strictly for experts only. The swell is way too big for the average punter. That trend continues into Tuesday the 8th, with another 12 ft to 10 ft S swell, clean and offshore, but again, only for the brave.

The real standout, and what I’d circle on the calendar, is Wednesday the 9th of September. The morning is pure magic: a 7 ft S groundswell (13-second period, energy of 1511) with glassy conditions. The wind is light, the waves are solid, and everything lines up for excellent surf. It’s still a sizable swell, best suited for experienced surfers, but this is the best wave on offer in the whole run. The afternoon goes onshore, so get out early.

After that, we’re back to the doldrums. Thursday and Friday the 10th and 11th are messy with onshore winds and dropping swell. Saturday the 12th offers a little relief with a clean 3 ft to 4 ft SSE swell and offshore winds, but it’s just a fun, small wave to finish the week. Sunday the 13th looks poor again.

So, to sum it up: the best windows are Monday morning the 31st of August for a clean, fun surf, and the absolute standout is Wednesday morning the 9th of September – glassy, solid groundswell, and a wave that will stick in your memory. Get on it.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
